Smart filament sensor

I added thicker walls to the encoder and changed the bearing circuit to fit.

This is an open source Smart Filament Encoder which detects:
- filament jams
- filament runout
- Hotend jams
- Nozzle clogs
- Partial nozzle clogs
- Filament tangles
- Overcontraints of the filament path (Under-extrusion)
- Under-extrusion
